Emerson / Artesyn / Astec MP1-3V-3V-3I-30-503 1000W Power Supply

The Emerson/Artesyn/Astec MP1-3V-3V-3I-30-503 is a 1000 W configurable power supply for industrial and commercial applications requiring multi-output DC conversion. Built on the MP1 chassis (2.5 × 8 × 11 inches), this unit accommodates up to seven intelligent DC-DC converter module slots, each delivering outputs from 2 V to 60 V. The -503 configuration includes three populated slots: two 42 V @ 12.5 A modules (Slot #1 and #2) and one 8 V @ 68 A module (Slot #3).
